A test automation team is evaluating two design approaches for their framework: a highly modular architecture with many small classes versus a simpler architecture with fewer, larger classes. The team values maintainability and ease of onboarding new team members. Which approach is more suitable?

Simpler architecture with fewer, larger classes

A balanced approach with moderate modularity

Use design patterns to reduce the number of classes

Objective: Apply Design Principles and Design Patterns in Test Automation CTAL-TAE Practice Questions (Page 4)

Part of the Domain 3: Test Automation Architecture domain, which makes up ~21% of our current practice bank. ISTQB does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–13 in this domain), expect 1–3 from this objective — we provide 25 practice questions to prepare you well beyond it.
